Comparing the TLEs for the ISS with epoch 13-SEP-06, 3:13:20 UTC with the ones of a day before (epoch 12-SEP-06, 4:25:20 UTC) at the time of epoch of the newer elements I find a difference of 34 km in position between the two. As NASA has not mentioned any orbit maneuvers for the ISS over the next few days are we seeing the kind of unwanted orbit tweak we saw a year ago during that mission of Discovery? (Was it due to some water dump or due to some special attitude maneuvering back then - I don't remember anymore?).
